The formula for circumference = 2[tex] \pi [/tex]r
Therefore we know that 25.12= 2[tex] \pi [/tex]r
To find the value of the radius, we divide 25.12 by 2[tex] \pi [/tex].
[tex] \frac{25.12}{2 \pi } [/tex] = 3.9979721705 or approximately 4ft.
In this case, 8ft would be the diameter instead of the radius.
